#     Fix root mounting with no mount options
#     
#     The "trivial conversion" in commit cccaa5e33525 ("init: use do_mount()
#     instead of ksys_mount()") was totally broken, since it didn't handle the
#     case of a NULL mount data pointer.  And while I had "tested" it (and
#     presumably Dominik had too) that bug was hidden by me having options.
